Is is gas tax deductible a valid tax write-off?

TL;DR

Gas expenses can be deductible if they are for business purposes.

Detailed Answer

Gas expenses are deductible when they are incurred for business purposes. This includes driving for work-related activities, such as meeting clients or traveling between job sites. However, commuting from home to your regular place of business is not deductible. For example, a self-employed consultant driving to a client meeting can deduct the gas expense, but not the drive from home to their office.

Where to Put It on the Tax Form

Schedule C (Form 1040), Line 9 for car and truck expenses

Real World Example

Calculation Required

A calculation is required for this deduction.

To calculate the deduction, you can use the actual expenses method, which involves tracking all vehicle-related expenses including gas, or the standard mileage rate provided by the IRS.

Audit Risk & Documentation Tips

Maintain a detailed mileage log, including dates, destinations, and purpose of each trip. Keep receipts for gas purchases and any other vehicle-related expenses to substantiate your deduction.
